max Tow Comparo - rear Dual Axle - Photo 05

While it’s possible to order 4:10:1 gearing separately (3.73:1 is standard), you’ll want to go ahead and check off the Max Tow Package on the option list. This not only gives you the lower gearing but also dual transmission oil coolers for $595. You might as well get the Protection Group, which is factory-speak for a transfer case skidplate for $50.
